3.4.2
Safety when using high pressure circuits
Here below are some basic indications regarding the high pressure circuit where the pump can be installed.
High pressure circuits should always be fitted with a safety or pressure relief valve.
Components of the high pressure circuits, particularly those that mainly operate outdoors, must be imperviousness to weather
conditions such as rain, frost or heat. All electrical parts should have adequate protection against direct or indirect sprays of water
and be suitable for use in wet environments.
High pressure hoses must be sized in accordance with the maximum operating pressure of the circuit and always within the field of
operation specified by the hose manufacturer. These precautions should also be respected for all the components found within
high pressure circuits. The ends of the high pressure hoses should be sheathed or, in any event, secured to a structure in order to
prevent dangerous whiplash in the event of a blast or a rupture in the connections.
Lastly, appropriately sized crankcases must be provided in order to protect the rotating component parts for the motion
transmission (flexible couplings and universal joints, belts, pulleys, etc.).
Check if there are any other safety instructions that must be followed in the Operating and Maintenance
Manual for the machine where the pump is fitted.
3.4.3
Rules of conduct regarding the use of high pressure lance
Here below are some basic indications regarding the use of the pump with high pressure lance equipment.
Those who operate high pressure nozzles must always put their own safety - as well as the safety of third parties likely to be
affected by their actions - before any other assessment or action in respect of the situation. Their work must always be guided by
common sense and an awareness of responsibility and precautions.
The operator must always acquire appropriate personal protective equipment (helmet with protective visor, waterproof overalls
and rubber boots) that guarantee good grip and stability on the ground in wet conditions.
Adequate clothing is effective against splashes of water, but cannot withstand the direct impact of water jets or splashes at close
range. In these circumstances, additional protection is recommended.
It is also desirable to have the operators work in teams of at least two people in order that they may provide mutual assistance in
case of need or danger, and have them organize an appropriate rotation that will provide cover in the event of long and tiring
shifts.
The area affected by the water jet must be prohibited and free from objects which, if hit by the jet, might be damaged or projected
elsewhere.
The jet should always be aimed in the direction of the workspace, including during preliminary or trial operations.
Attention must always be paid to the trajectory of debris removed from the jet. If necessary, anything that might be exposed to the
jet should be given adequate protection.
The operator should not be distracted for any reason while carrying out his or her work. Those wishing to enter the workspace
must wait for the operator to suspend work on his or her own initiative and make their presence immediately known.
Team members must always be aware of each other’s intentions in order to avoid potentially dangerous situations.
The system must never be started-up and pressurized before each team member is at their own station and the operator has
aimed the jet into the workspace.
Check if there are any other safety instructions that must be followed in the Operating and Maintenance
Manual for the machine where the pump is fitted.
3.5
Safety during handling and lifting
Before starting, make sure the area designated for the work is organised so that the materials can be
lifted and moved safely.
The unloading, loading, handling and lifting must be carried out by authorised, qualified personnel who
have completed specific professional training.
People who are not involved in the handling and lifting work must remain at a safe distance throughout
the operation.
